How to Use This Calculator

Enter the number of crew members in the habitat.
Set the mission duration to apply pressurized volume standards (NASA: 25 m³/person minimum for long duration).
Input any dedicated volume for specific functions: lab, medical, exercise.
Review the minimum total pressurized volume and recommended habitable volume.
Compare to your habitat design volume to identify if additional modules are needed.
